Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation) & Framework 'Flutter' not found

Question

I'm facing an issue while building my Flutter app for the iOS simulator. The build fails with the error:

vbnet
Copy
Edit
Error (Xcode): Framework 'Flutter' not found
Error (Xcode): Linker command failed with exit code 1
I've tried the following steps:

Recreated the ios/ folder and cleared derived data.
Ran flutter clean, reinstalled CocoaPods (pod deintegrate and pod install).
Verified AppDelegate and framework paths in Xcode.
Ensured the deployment target is set to 14.0 in the Podfile.
Despite these efforts, the issue persists. I'm using the latest Flutter SDK, Xcode, and macOS versions. Any guidance to resolve this would be greatly appreciated

Performed flutter clean, removed and reinstalled Pods (pod deintegrate, pod install). Deleted derived data using rm -rf ~/Library/Developer/Xcode/DerivedData. Recreated the ios/ folder. Updated CocoaPods and ensured all dependencies in pubspec.yaml are up-to-date. Verified AppDelegate.swift and ensured Firebase setup (added FirebaseCore initialization in AppDelegate.swift). Despite these efforts, the issue persists. Initially, I managed to resolve it by running these steps in sequence:

bash
Copy
Edit
flutter clean
rm -rf ios/Pods
rm -rf ios/.symlinks
rm -rf ios/Flutter/Flutter.framework
sudo gem install cocoapods
pod repo update
cd ios
pod install
flutter upgrade
flutter pub get
cd ios
pod deintegrate
pod install
rm -rf ~/Library/Developer/Xcode/DerivedData
flutter clean
flutter pub get
cd ios
pod install
cd ..

This fixed the issue temporarily. However, after two days, I faced errors in Firebase phone authentication. I added FirebaseCore initialization in AppDelegate.swift, which resolved the Firebase error but reintroduced the "Framework 'Flutter' not found" error.

I’m seeking guidance to resolve this persistent issue once and for all. Any insights or suggestions would be greatly appreciated!
